Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a hinged cap for covering a container of food or the like, and more particularly, a hinge made of synthetic resin capable of indicating that unauthorized opening has been performed. It is related to the attached cap.

[Prior Art] Today, a hinged cap in which an upper lid and a lid main body are connected to each other by a hinge portion can open a container only by pushing up the upper lid, and therefore, it is easy to pour out a content liquid or the like at the time of use.
It is used a lot.

This hinged cap has an opening removing portion formed by an annular cutting line on the top plate portion of the lid main body, and a pull ring is integrally provided with the opening removing portion, so that the pull ring is pulled up at the time of initial opening to cut the opening. The container is opened by breaking along the line and removing the opening removing portion by breaking.

As described above, in a general hinged cap, the spout is closed by forming the opening removal portion that breaks and opens at the time of use on the top plate portion of the lid body, and thus foreign matter can be mixed into the container. Although it is impossible to prevent this, in order to prevent tampering more effectively, a hinged cap having a function capable of clearly indicating whether or not the upper lid has been opened has been demanded today.

As shown in FIG. 9, a hinged cap that can indicate that the upper lid has been tampered with is formed on the side wall portion 45 of the upper lid 41 having the opening protrusion 59 at a position facing the hinge portion 17, as shown in FIG. A cut line 53 is provided in the vicinity of the unsealing protrusion 59 to form a breakage removal portion 51, and an inward engaging projection 57 is formed inside the breakage removal portion 51, while the lid body 12 is provided. On the outside of the spout wall portion 26, etc. formed on the
To form an inner engaging protrusion 57 formed on the inside of the breakage removing portion 51 below the outer engaging protrusion 29,
Thus, the upper lid cannot be opened unless the breaking removal portion 51 is removed from the upper lid side wall portion 45 by gripping the pull tab portion 55 attached to the breaking removal portion 51 (for example, Japanese Utility Model Publication No. 58-3.463).
Or, when opening the upper lid, a protective cover is formed to cover the opening projection for pushing up the upper lid, and this protective cover is connected to the side wall portion of the lid body by a bridge or the like, and when opening to open the upper lid, What removes the protective cover from the lid body and pushes up the opening protrusion (for example, JP-A-62-78.064), and further forms a minute protrusion in the upper lid immediately below the opening protrusion to cover the lid. Breakable and removable engagement is formed on the side wall of the body, and the minute protrusion is engaged with the engagement so that the engagement is broken and removed from the lid body when the upper lid is opened. (For example, Jitsukai Sho 63-21.252).

[Problems to be Solved by the Invention] Synthetic resin hinged caps are mass-produced by injection molding today, but the hinged caps are produced with the upper lid open in view of the shape and mold production. And after molding,
The upper lid is closed.

By the way, as described above, the breakage removal portion is formed on a part of the upper lid side wall portion, and the inner engagement protrusion is formed on the breakage removal portion,
To engage the outer engaging protrusion formed on a part of the lid body with the inner engaging protrusion provided on the upper lid, and
In the case where a minute protrusion is provided near the opening protrusion for pushing up the upper lid, and a breakable engaging portion that engages with the minute protrusion is formed in a part of the lid body, If the outer protrusions or the minute protrusions are formed to be large, there is a risk that the protrusions or the protrusions may be fractured when the protrusions are engaged with each other or the minute protrusions are engaged with the engaging portion when the cap is closed after molding. If the portion or the minute protrusion is made smaller, the engaging force becomes smaller, and there is a drawback that the broken portion is opened without breaking at the time of illegal opening. It should be noted that the one provided with a protective cover for covering the opening protrusion for pushing up the upper lid also opens the protective cover without breaking when the protective cover and the opening protrusion are engaged when the upper lid is closed after molding. It was difficult to close the top lid to engage the projections.

[Means for Solving the Problems] In the present invention, in a hinged cap in which an upper lid portion and a body portion are connected by a hinge portion, a male screw portion is formed on an outer side of a side wall portion of the lid body portion, A cylindrical outer cylinder is attached to the lid body composed of the main body and the main body, and the outer cylinder connects the upper half and the main body with the hinge portion, and A female screw portion that is screwed with the male screw portion is formed so as to be movable in the vertical direction with respect to the lid body, and a pill-proof band portion is formed at the lower end of the outer cylinder body portion via a bridge portion. When the pill-proof band portion is engaged with the lower end of the side wall portion of the lid body, the height of the hinge portion of the outer cylinder is set to be lower than the height of the hinge portion of the lid body.

[Operation] The hinged cap according to the present invention is provided on the outside of the lid body composed of the upper lid portion and the body portion that are integrated by the hinge portion,
Since the cylindrical outer cylinder in which the upper half part and the main body are integrated by the hinge part is provided, the position of the hinge part of the lid and the position of the hinge part of the outer cylinder are shifted in height and in the horizontal direction. By doing so, it is possible to prevent the upper lid portion of the lid body from being pushed up and opened.

Also, the upper lid can be opened by aligning the height of the hinge of the lid with the position of the hinge of the outer cylinder.
A pill-proof band portion is formed at the lower end of the outer cylinder via a bridge portion, and the pill-proof band portion is engaged with the lower end of the side wall portion of the lid main body to thereby make the hinge portion of the outer tube in the lid body. Since it is supposed to be located below the hinge part, if the hinge part of the outer cylinder is made to be at the same height as the hinge part of the lid for opening, the bridge part will be broken and the upper lid part will be opened. be able to.

[Embodiment] A hinged cap according to an embodiment of the present invention is one in which a cylindrical outer cylinder is fitted to a lid body in which an upper lid portion and a main body portion are integrally formed by a hinge portion.
